Using A Function To Create A "Case IN-SENSITIVE" Search?

Nov 9, 2010

I am a beginner in programming however I am close to completing this task for my uni course and I know what method is needed "toLowerCase()" yet I am not sure on where it needs to be placed. :confused: If i paste in the question and then the coding I have done so far to discover if string s appears in any of the URLs in the array pages. Gives an alert of s together with 'found' or 'not found' as for find1C. [Note that the search should be case insensitive so that 'lboro' and 'Lboro' and 'LBORO' would all be found in [URL]... all remaining functions should also be case insensitive in this way]

[Code]...

Removing Case Sensitive When Comparing Form Fields?

Jun 20, 2011

I'm trying to make my form both check that the e-mail's match and also be case insensitive when being submitted. I've figured out how to get the e-mail's to be checked to match, but can't figure out how to also make it not case sensitive.

This is what I have so far...

<head>
<script type = "text/javascript">
function checkSame() {
var emval1 = document.cform.email.value;

"Case Sensitive"

Jul 23, 2005

This script is designed to remove foul language from a document, the
question is that it will only remove what is put into the array, these
words are in lowercase, now how can I have the script parse the document
in lowercase?

If foul words start with a cap or their in uppercase the script won't
remove them.

I tried putting .toLowerCase(); into different parts of the script and
it powered me off a few times.

AJAX :: Make A Search Case Insensitive?

Apr 19, 2011

I am working on a search function to call some data from an XML document. It works fine except for the fact that it's case sensitive.

What method do I need to use from the String object to make it case insensitive, so that a J is the same as j?

I was thinking of changing my text box string to all lower case using toLowerCase(). If I did this, then would I have to do the same thing in the info retrieved from the XML document? I want to make it so that Tom is the same as tom - I'm just wondering where I would have to apply these - to both the XML doc (being read for the output) as well as the text box string (the input).

Just wondering if I'm overthinking this, or on the right track with toLowerCase().

Also, in my search, to filter the results from only entering a few letters (not the entire element, I'm using the substr() method. It seems to work but I don't know if this affecting the case somehow...

Search And Replace Body Text With Lower-case Text

Apr 19, 2010

The javascript below is looking for the word 'margaret thatcher' in the body and surrounding it with a link. It's lower-case but the script is ignoring the case so that won't matter. But, the problem is that because Margaret Thatcher is a proper noun, it will be capitalized in the body text yet replaced with lower-case text. How can I modify this script to look for the word while ignoring the case but use the same text it found as the replacement instead of using the text object?

Create A Search Bar From Database?

Mar 24, 2011

I was assigned to find out how to do this for my work. We were hoping for a javascript (but it could be PHP or other comparable format). Instead of the search function searching the website, we would like it to search a small database full of information.

I have been reading for days now and have just gotten more confused. One thing I read (hopefully it was true) is that you can save a database as an HTML, then convert HTML to .JS which javascript will run.

How To Create A Site-Level Search Applet???

Jul 20, 2005

Can anyone point me to a good tutorial for creating a site-level
search applet? I am trying to create a virtual catalog of sorts, and
I would like to be able to search the catalog and have the results
displayed on the same page with one column text and an image of the
product. I've seen several tutorials that create site-level searches
that will bring back a search results page with options to choose
from. I am looking to create a search that does not bring back this
"results" page, but displays an image of the product instead. Given
the nature of the products, search results will only bring back one
specific item, and so, I would like to skip the "results" page
altogether. Any thoughts?

Object Oriented JS - OO Programming - Create Search Objects Or Arrays

Feb 10, 2011

Trying to figure out OO programming for JavaScript and I'm totally lost.

Here's what I'm trying to do:

I'm posting search data to a PHP form to run a query on a database.

The structure is sort of like this:

So I'm thinking I need to create search objects or arrays. Initially, I thought I could do something like this:

Code:

This doesn't seem to work. It says object not defined whenever I try to do something.

I've also tried creating a JSON object like this:

Code:

This will allow me retrieve the data like I want to:

Code:

The problem is I can't figure out how to add data to the JSON object without manually typing it in. I need to be able to loop through form elements on my HTML page and set them to these variables. I'm using jQuery and doing something like this:

Making Expanding Menu Hierarchy Sensitive?

Mar 17, 2010

I'll get to the hierarchy sensitive part next, but for now I need help making this even work with two top-level links. I'm building a left-navigation that's expandable. Click a little + box image to the left of a top-level section's link, and all the links to sub-sections within that section expand out, the + box image becomes a - box image, and clicking the - box collapses the sub menu links. The scripts below work so long as I just have one top-level section, but because they us an ID for the +-box image, when I add a second top-level menu item, the swapImage function no longer works. How do I make it work with a class instead of an ID? The JavaScript and HTML code is below:

Form Delay And Redirect / Sensitive Field?

Jan 30, 2009

Ive created an asp based sign on page with codebehind. Basically how it works is when the submit button is clicked, it triggers an event which captures the values the user has entered, writes out a new form and passes these values to the appropriate fields in the form, and finally I have javascript which automatically submits the form. It works, but i have a few issues..

[Code]....

Also, the other issue...If I comment out the auto submit javascript and log in (it then writes out the form waiting for me to submit before moving to secure side) I can view the html source and actually see the values entered into the field. Of course, with the javascript not commented out the form submits as soon as it is written out so the user never sees it, but I'm thinking this could still be a security risk? Can I make these values invisible somehow?

Cannot Get Search To Function

I created a search where I use AJAX to send a request to a MYSQL database using PHP. I am able to get the two to talk. You can click the search button and the "results" will display.

Can't Get Regex To Work - Search() Function

Dec 14, 2005

I've been having a lot of trouble trying getting the following code to work, all the examples that I have seen tell me that it should, but it doesn't and i'm out of ideas.


if (parent.input_frame.input_form.cheque_number.value.search(/./) != -1)
{
alert('The cheque number is invalid.');
parent.input_frame.input_form.cheque_number.select();
return;
}

What I want it to do is alert the user that the cheque number they have entered is invalid if it contains a period / full stop / dot.

The problem is that it always says the cheque number is invalid no matter what the user enters.

I have spent the last hour or two trying a number of things using just about all the regex functions and examples in the JavaScript book I have and examples from other posts on this site, but still cannot get it to work.

If you could let me know what I am doing wrong or provide me with an example of another way to do this that would be great.

Browser is Internet Explorer, have tried /D/ as the regex too, but this did not trigger the alert when a number with a dot was entered.
